' METALLIC CREEL.

1,026,646, Specification of Letters Patent. Patented May 21, 1912 Application filed August 20, 1910. Serial No. 578,155.

To all whom it may concern:

Be it known that I, CHARLES A. ALLEN, a citizen of the United States, residing in Linwood, county of Worcester, and State of Massachusetts, have invented certain new and useful Improvements in Metallic Creels, of which the following is a full, true, and complete specification.

This improvement in metallic creels relates to a simple, durable and practicable construction of sheet metal creels, wherein ordinary porcelain skewer steps can be safely held in a positive manner without danger of fracture and with facility for prompt removal and renewal when worn out, as will appear in full in the following description and in the illustrative drawings forming part hereof.

Figure 1, is a cross section of a metallic creel of common design; Fig. 2, is an enlarged vertical section of one of the step bearings thereof constructed in accordance with this invention; Fig. 3, is a similar view showing the parts separated and the skewer step in elevation, and Fig. 4, is a plan view.

It will be understood by those skilled in this art that the creel of a spinning or like machine forms the support for the bobbins which supply the yarn upon which the machine works. The bobbins, marked 1, in Fig. 1, are removably carried on skewers 2, which are placed in the step hearings on the creel plates or rails of the creel with their top portions inserted and suitably held in apertures or recesses in the plates, or rails above, so that the skewers and their bobbins may rotate freely as the yarn is withdrawn.

According to the present invention the several creel plates, marked 3, are formed of thin sheet metal with marginal reinforcing flanges and are mounted on the upright posts 1 with provisions for vertical adjustment thereon, so that the space between the upper and lower creel plates can be set in accordance with the length of the skewers. The lower creel plates on which the skewers are stepped are provided with a plurality of punch holes 5, corresponding with the number of skewers to be supported thereon, and for each punch hole there is provided a metallic, cup-shaped receptacle or socket having a rim-boss 7 formed on its upper margin which is inserted in the punch hole, from the underside of the plate, and upset therein and over the edge of the hole. The rim boss 7 is formed by a reduction of the upper outside diameter of the cylindrical socket 6, which leaves a square shoulder as shown, to be drawn firmly against the underside of the plate by the upsetting operation, thereby securing the socket against rattling as well as lateral displacement. The upsetting of the rim boss upon and over the margin of the perforation is conveniently accomplished by a rotating tool, although it may be done otherwise, so that the edge of the socket is smoothed and slightly rounded when completed, being in this form the least likely to catch and retain dirt, while the roughly punched perforations in the creel plate do not require to be trimmed or smoothed because they are covered up by the rim of the socket. The porcelain skewer steps, such as shown at 8, are secured in the sockets 6, within a lining 9 of yielding cementitious material, such as shellac or putty, which protects them against fracture by contraction of the metallic socket due to change of temperature, and also hold them positively in place. The bottom wall of the socket forms a positive and rigid base or support for the skewer step to rest upon, and in order that the latter may be removed when worn out an ejector hole is provided in the bottom of the socket, as shown at 10. It will be understood that a sharp pointed instrument is adapted to be thrust upwardly through this ejector hole in order to drive the porcelain step from its seat.

Having'described my invention, I claim the following:

1. In a creel, the combination with a sheet metal creel-plate having a plurality of punch-holes through the same, of a plurality of metallic, cup-shaped receptacles, formed with rim bosses inserted within and upset over the edges of the punch-hole in said creel plate, and porcelain skewer steps supported within said receptacles with their step bearing surfaces substantially flush with the surface of the sheet metal substantially as set forth.

2. In a creel, a sheet metal creel-plate having a plurality of punch-holes through the same, a corresponding plurality of metallic, cup-shaped receptacles having rimbosses, respectively upset in said punchholes, in combination with a skewer step occupying each said receptacle and a cementitious lining in the annular space between said step and the Wall of its receptacle.

3. In a roving creel, a sheet of metal flanged at its margins and punched with a plurality of punch holes, metallic cupshaped receptacles riveted by their upper margins in said punch holes and provided with apertures in their bottoms, and porcelain skewer steps seated in said receptacles with their step-bearing surfaces substantially flush with the metallic sheet and adapted to be ejected therefrom by thrusting an implement through the said aperture.

In testimony whereof, I have signed this specification in the presence of two wit- 15 Copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents Washington, D. G.
